One of the quirkiest spas in Cape Town. A love-it-or-hate-it-environment, Sanctuary is designed to mimic a subterranean cave, complete with fake rocks and water features, and lit by neon and candlelight, like entering the lair of one of James Bond’s archrivals. The three-hour Moonlight Treatment starts with sparkling wine and a picnic basket and ends with a stone massage, all by moonlight. They have Cape Town’s only Rasul Chamber, and there’s a salt water flotation tank, too. It can feel a touch claustrophobic if you prefer light-filled, open-air spaces, but to compensate, two glass-enclosed massage gazebos have been erected amongst the fynbos vegetation on the mountain slopes.
